For security reasons, the raw cryptographic key material represented by a CryptoKeyVersion can never be viewed or exported. It can only be used to encrypt, decrypt, or sign data when an authorized user or application invokes Cloud KMS.

CryptoKeyVersionTemplate

A CryptoKeyVersionTemplate specifies the properties to use when creating a new CryptoKeyVersion, either manually with CreateCryptoKeyVersion or automatically as a result of auto-rotation.

ImportJob

An ImportJob can be used to create CryptoKeys and CryptoKeyVersions using pre-existing key material, generated outside of Cloud KMS.

When an ImportJob is created, Cloud KMS will generate a "wrapping key", which is a public/private key pair. You use the wrapping key to encrypt (also known as wrap) the pre-existing key material to protect it during the import process. The nature of the wrapping key depends on the choice of import_method. When the wrapping key generation is complete, the state will be set to ACTIVE and the public_key can be fetched. The fetched public key can then be used to wrap your pre-existing key material.

Once the key material is wrapped, it can be imported into a new CryptoKeyVersion in an existing CryptoKey by calling ImportCryptoKeyVersion. Multiple CryptoKeyVersions can be imported with a single ImportJob. Cloud KMS uses the private key portion of the wrapping key to unwrap the key material. Only Cloud KMS has access to the private key.

An ImportJob expires 3 days after it is created. Once expired, Cloud KMS will no longer be able to import or unwrap any key material that was wrapped with the ImportJob's public key.
